For thepurpose of reciprocating the yoke .i4 and the movable switch-contacts oonneeted thereto seid yoke is eonneeted. by rneens'of e. ple-te 25 to en interniediete point on tbe lever 25, which is pivotelly Connected et its end to'suitable supporting-plates 27, projecting from the rear Wall le oi the mein support. The lever 26 is mede up of two separate plates Wliieli pass onvopposite sides of the plete 25, and n connection there- Witn is mede by ineens oi e pin and e slot 29. The slet is neces-serv tol permit the emiten-contacts to move vertieelly in resoonse-to the Uuiclin action or" the o enin s in' the insulating-'plete 1G, through which tbe supporting-rods 13 pass.A The forward end ofthe lever 26 is connected to en operatinglever 30 by Ineens of s. pin-endslot connection comprising e pin 3i and e slot 3L. The levers 26 and 3() ere also connected by mee-ns of e eoilel spring 33. 30 is pivotecl et the point 3e betwe n upriglits 35, carried et the iront one el' side flanges 15, by means oi e t:1.:isv;. plete 36, wln'eli connects these il bers.
